Cover crops have many benefits for farmers, including erosion control, weed suppression, and feeding the food soil web. Cover crops also play an important role in fertility, particularly for nitrogen.
One of the challenges facing farmers who use cover crops is quantifying the available nitrogen supplies to the following cash crop by the decomposing cover crop residues and how they might change their fertilizer management to account for this. This publication is intended to educate farmers on the nitrogen cycle, cover crops, and nitrogen; how nitrogen is released from cover crops; and the new Cover Crop Nitrogen Availability Calculator, including the steps necessary to use the Calculator.

2022 plant disease losses, including control costs, amounted to an estimated $933 million. The value of the crops used in this estimate was approximately $8200 million, resulting in a 11.4% relative disease loss across all crops included in this summary. The estimated values for most crops used to compute these disease losses are summarized in the UGA Center for Agribusiness & Economic Development 2022 Georgia Farm Gate Value Report (AR-24-01). Some estimates for fruits, ornamentals, and turf rely on Extension specialists’ knowledge of the industry and industry sources for information.

Variety selection is one of the biggest decisions and investments cotton growers make each year. In 2010, the UGA Extension Cotton Agronomists implemented the UGA On-Farm Cotton Variety Evaluation Program to assist in this decision. In this annual publication, varieties were evaluated in 2020 across a wide range of environments in the cotton producing regions of Georgia in cooperation with county agents and industry partners. The implementation of this program has made a tremendous impact on variety selection from year to year, and it will continue to have the same impact in the future.

With the passage of the 2018 Agriculture Improvement Act, the federal government removed industrial hemp from the list of Schedule I drugs and opened up opportunities for farmers to produce this once widely grown crop. Although the brief guide that follows is not exhaustive, it is meant to provide basic information for growers who are considering hemp production of floral materials meant for the cannabinoid market. Cannabinoids may include CBD, CBG, etc. Due to the changes in rules and regulations that are likely to occur, we recommend readers look to the Georgia Department of Agriculture and the USDA for any clarification or questions they may have regarding the regulation of hemp production in Georgia.
